Irish dance was practiced mostly among the Irish until the mid-1990s, when Riverdance took the world by storm. The theatrical dance show, starring Irish-American dancer Michael Flatley, brought Irish dance to the masses, and there is still interest in it. Look no further than Petaluma’s Keenan Irish Dance School for proof. The school’s students will show off their rhythmic steps at the Luck of the Irish show on March 17 at 5:45 p.m. at the Petaluma Veterans Building in Petaluma. Tickets, which are $20 for adults and $10 for kids, will be available at the door. See tinyurl.com/yvj5xem9.
